Bolt happy to thunder into retirement

Jamaican sprint great Usain Bolt said he has no regrets about his decision to retire from athletics in 2017 because he has accomplished everything he wants to in the sport.

Bolt will hang up his spikes following the world championships in London in August, bringing down the curtain on a career that has delivered eight Olympic gold medals.

"I've done everything I wanted to do in the sport ... there's nothing left to accomplish," Bolt said on the red carpet at the Laureus World Sports Awards in Monaco on Wednesday, where he was named Sportsman of the Year.
